The invention relates to a process for recovering a precious metal, particularly palladium, from a non-aqueous effluent comprising the metal and dissolved salt and/or polyether contaminants, wherein the effluent is contacted with a reduction agent, the precious metal is deposited onto a carrier, preferably comprising a combustible carbonaceous material, and the metal loaded carrier is separated from the effluent.

Recovery of precious metals from catalyst residue

A continuous process for the preparation of an alkyl propionate, which comprises reacting an alkanol in a liquid phase with ethene in a reaction vessel in the presence of a carbonylation catalyst, and removing alkyl propionate from the reaction vessel in a stream of vapor.
